SiO
2-P adsorbent material impregnated with an extractant is packed into a column. Solution containing MA (
![1](../../img/1.gif)
) is fed into this column, and MA is adsorbed. The adsorbed MA is eluted by a suitable eluant (
![2](../../img/2.gif)
), and recovered into a solution (
![2](../../img/2.gif)
'). Several columns with different adsorbents (extractants) may be used for better separation of MA from other elements.
